lawnmower problem

AB_Monterey · 06-05-2011, 09:19 PM

Hmmm. I've never treated any fuel in any of my lawn equipment and never had an issue starting them.

My push mower is a Honda that is easily 20 years old and starts on the first pull EVERY time. It's due for it's 10 year oil change. Plug change? Maybe another few years. Walmart mower? I'll pass. Tractor, chainsaw, weedwacker, leafblower, never an issue with any of them.

I must be walking around lucky.

Yep, you are. Reminds of the guy who said he's never had a flat tire and then the inevitable happens.....

As far as the 10 year oil change, coming from my perspective that's criminal in my book

A quart of SAE30 costs about $3 and is a 5 minute job.....

Ok, it looks like the problem was with the oil saturated air filter. It is a foam style air filter so soaking it in paint thinner cleaned out the oil and dirt, and after letting it air dry for about 30 minutes, the power up-power down problem was fixed. A squirt of carb cleaner was shot into the carburetor with the filter off and whether that was any help is an unknown but it didn't hurt.

I over-filled the oil change with a little too much oil and probably the engine sprayed it up through the carburetor and into the air filter. The engine sensed the lack of air coming through the filter and opened up the choke plate which is why it was going through a power-up, power down back & forth what with a clogged filter and the choke making automatic adjustments.

There will be a pop quiz on all this tomorrow at 10-am!

And, it's a Weed Eater 22", $129 Wal-Mart lawnmower on it's third season now. Wal-Mart warranties them for 90 days, and I managed to destroy the engine on the previous mower on about the 85th day by hitting a rock with the blade, and Wal-Mart didn't bat an eye about replacing it with a new mower because I had the receipt! Rots-o-ruck trying to do that at Aubuchon's. Gosh, what was life like before Wal-Mart?

Ah, I think you need a new mechanic.

Actually, Walmart sells a lot of power equipment and tools that are made right here in the USA.......sure, some are American brands that are manufactured in China but some are made here, also.
And Mark is right.....I fill my tanks, add Stabil, run them a bit to mix it up and they all start right up in the spring....everything from weed whackers to your boat. Also helps to line everything up, powerwash and spray on a little oil before storage.

When I brought my snowblower carb to my local repair guy not too long ago, he recommended the following:

1. For any small engine, buy at least 89 octane.
2. When you buy your gas for your small engines, add a small amount of fuel stabilizer. Always.
3. For off-season storage, drain as much fuel as you can, add stabilizer to the tank. Run the engine so the stabilizer gets into the carb.
4. To prepare for on-season use, fill the tank with some nice fresh fuel. Don't add stabilizer to this, as there is some still in the tank from storage.
5. Make sure you use the higher octane fuel with stabilizer.

He recommended this for all small engines. 4-strokes (snowblower, lawn tractor/mower) as well as 2-strokes (chain saw, weed wacker etc).

Ever since I started doing this I have not had any problems. *knocking on wood*

Well, it's not used that much. I'm lucky if it's got more than 10 hours on it over the last 10 years. There's one area of the yard that is impossible to get with the tractor. I cut that with it and not much else.

That said, it is getting a change this summer.

This Honda is amazing. My wife bought it second hand before we met. It was a few years old then. I had to do the first repair on it last week. Had to replace the starter rope. It broke up north at camp and I started the thing by using a shoe string so I could finish and get it home. Amazing.

As for the gas issue, other than the unique issues with boats, gas will not go bad that quickly, even with ethanol. A few months should not be an issue. My two classic cars start right up every spring without issue and all I do is change the oil and fill the tank in the fall.

I've been running my lawnmowers, leaf blower, snow blower and trimmer dry of gas for years before putting them away. Nothing EVER gas related at start up...never ever...At the beginning of the season the machine is needed I fill it up press the primer bulb a few times and the engine starts with a couple pulls. I'm a firm believer in draining them, some people are not. To each his own I guess...
